The Double layer 6 mil 4 year greenhouse film, with Inflation Fan Kit, allows for superior heat retention. Poly latches are included and the "Twist of the Wrist" roll-up sides make ventilation easy. Heavy-duty double doors come complete with stainless steel hinges and latch. An optional second door kit is also available.
